When I started I decided to provide the girlfriend experience, because my roommate told me theres more to make.
How do I separate my own self from my GFE 'self'? It's kinda getting to me. I don't really want to stop escorting right now because of the bills and tuition.
What specifically is getting to you? Are there services (e.g. kissing) which you don't want to do? It's okay to remove services from your list. If that means you have to drop your price by a tenner an hour, so be it. Surely it's better to get ?30-50 less per day but feel like you're looking forward to bookings rather than dreading them?
It's all very well saying "X service brings in more money" but if you hate doing that service then you'll end up burning out and turning down bookings just because you don't want to do them. If it was that easy then we'd all be offering anal, hardsports, hardcore BDSM etc. But that just isn't sustainable.
If the issue is more about a line of demarcation between "real" you and "work" you, these are the things which helped me.
Firstly I sat down and wrote a brief biography of my work self. Date of birth (important for me as I knock some years off my age), where grew up, where went to uni and what studied, relationship history, family situation, hobbies, etc etc. Some of the facts are from my real history, but everything around my family is complete bullshit.
After this I decided on choosing a personal style for when I'm going on bookings. In my every day life I dress in trainers, jeans and t-shirt 90% of the time and don't bother with makeup and have my hair pulled back in a ponytail. I started with one dress, one set of underwear and one suspender belt and stockings (I'm old school haha) and one set of earrings and necklace (make sure if you wear a necklace to bookings that it's a thin chain that will snap if pulled too hard.) From there I expanded slowly so I now have about 8 sets of matching lingerie and 4 dresses which I rotate through depending on mood and any special requests. I also now have 3 sets of jewellery for wear in bookings.
In bookings I use men's aftershave as my scent, which my clients prefer for discretion. I have bought some bits of makeup and followed some tutorials on Youtube and I now have a specific style that I use for work. I don't use the aftershave if I'm not working. This is a really big one for me because smells to me are the most evocative of the senses and have the most emotional resonance.
I have become very practised at mentally and emotionally sealing off the different parts of my life. Some of my work style has now bled through into my personal life, and I'm completely comfortable with that, it doesn't bother me at all. I also find some aspects of my work personality - the ability to set and enforce boundaries - has also come over and that is very much a good thing, as it's something I struggled with before.
